Microsoft AT-Scheduler Service (ATSVC)

This is a DCE/RPC based protocol used by CIFS hosts to access/control the AT-Scheduler Service across a network. This dissector is described by an IDL file and is automatically generated by the Pidl compiler.

History

This protocol first appeared in Windows NT4 and is used to access the scheduler service across a network.

Protocol dependencies

DCE/RPC: This protocol is implemented ontop of the DCE/RPC transport. This protocol is often access from the \PIPE\atsvc named pipe on IPC$ but can also be reached through a dynamically assigned TCP port. Accessing this service using TCP as transport requires the support of the EPM Endpoint Mapper service.

Example traffic

Wireshark

The ATSVC dissector is fully functional.

Preference Settings

There are no preference setting specific to the ATSVC protocol.

Example capture file

XXX - Add a simple example capture file to the SampleCaptures page and link from here (see below). Keep this file short, it's also a good idea to gzip it to make it even smaller, as Wireshark can open gzipped files automatically.
